Differences in gut microbiota composition between obese and lean children: Discussion during SFA congress next Nov. 7


Recent evidence suggests that our gut microbiota is involved in energy regulation as well as inflammation, and should therefore be considered as an environmental factor playing a role in the pathophysiology of obesity. Although energy intake can affect the gut microbiota composition, it is still unclear whether and which gut microbiota play a role in the development of obesity in humans. Recent studies in humans and mice have already shown that obese and lean subjects have a different gut microbiota composition mostly present at the phylum level, i.e. mainly Firmicutes and Bacteroidetes. However, only a few studies have investigated the prevalence of these bacterial phyla in the faeces of obese children and adolescents. Due to limited and contradictory findings with regard to the composition of the gut microbiota in obese children, further in-depth analysis of the role of the intestinal microbiota in childhood obesity is warranted. The principal aim of this study was to evaluate and compare the presence of certain gut bacterial phyla, genera and species in faecal samples of obese and lean children.
